Fluorescence spectroscopy on moving particles


An optical lab-on-a-chip system is presented that enables fluorescence spectroscopy on moving biological particles. Our compact pathogen detection platform combines a fluidic channel with a chip-size, distributed spectrometer that is optimized to record fluorescence spectra from moving analytes. Large-volume, continuous fluorescence excitation is achieved by incorporating the fluidic channel into an anti-resonance waveguide that accommodates either laser diodes or LEDs. Simultaneously monitoring total intensity and spectrally-resolved emission yields accurate spectra for pathogen discrimination.
